Brief Analysis of the Practical Application of Polyimide Film

Polyimide zaj duab xis yog ib qho ntawm cov khoom lag luam ntxov tshaj plaws ntawm polyimide, uas yog siv rau qhov rwb thaiv tsev ntawm cov motors thiab cable wrapping cov ntaub ntawv. Cov khoom tseem ceeb yog DuPont Kapton, Ube’s Upilex series thiab Zhongyuan Apical. Pob tshab polyimide zaj duab xis ua haujlwm raws li kev hloov pauv hnub ci vaj huam sib luag. Lub nkoj ntawm IKAROS yog ua los ntawm polyimide films thiab fibers. Hauv kev tsim hluav taws xob thermal, polyimide fibers tuaj yeem siv los lim cov roj kub, thiab cov xov paj polyimide tuaj yeem cais cov plua plav thiab cov khoom siv tshuaj lom neeg tshwj xeeb.

Txheej: Raws li cov xim pleev xim rau cov hlau nplaum hlau, los yog cov xim kub resistant.

Advanced composite materials: used in aerospace, aircraft and rocket components. It is one of the most high temperature resistant structural materials. For example, the supersonic passenger plane in the United States is designed to have a speed of 2.4M, a surface temperature of 177°C during flight, and a required service life of 60,000h. It is reported that 50% of the structural materials have been determined to be thermoplastic polyimide as the matrix resin. of carbon fiber reinforced composite materials, the amount of each aircraft is about 30t.

Fiber: Lub modulus ntawm elasticity yog qhov thib ob tsuas yog carbon fiber, uas yog siv los ua cov khoom siv lim dej rau cov xov xwm kub thiab cov khoom siv hluav taws xob, nrog rau cov mos txwv thiab cov ntaub thaiv hluav taws. Ntau yam khoom siv polyimide yog tsim nyob rau hauv Changchun, Tuam Tshoj.

Ua npuas ncauj yas: siv los ua cov khoom siv rwb thaiv tsev kub.

Engineering plastics: Muaj cov thermosets thiab cov thermoplastics. Cov thermoplastics tuaj yeem yog compression molded lossis txhaj tshuaj molded lossis hloov molded. Feem ntau yog siv rau nws tus kheej lubricating, sealing, insulating thiab cov khoom siv. Guangcheng polyimide cov ntaub ntawv tau siv rau txhua yam khoom xws li compressor rotary vanes, piston rings thiab tshwj xeeb twj tso kua mis seals.

Separation membrane: siv rau kev sib cais ntawm ntau yam roj pa, xws li hydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen los yog methane, thiab lwm yam, kom tshem tawm cov dej noo los ntawm huab cua hydrocarbon pub roj thiab cawv. Nws kuj tseem siv tau ua pervaporation membrane thiab ultrafiltration membrane. Vim lub tshav kub tsis kam thiab cov organic hnyav tsis kam ntawm polyimide, nws yog ib qho tseem ceeb tshwj xeeb hauv kev sib cais ntawm cov organic gases thiab kua.
